该成像系统还包括主控器 2， 该主控器 2—般可以采用 DSP (数字信号处理器)， 主控 器 2与二个摄像头的微控制器通讯连接， 以向各微控制器发送指令，各微控制器接收到来 自主控器 2的指令后会将其转换为自身的指令，并据此对与各自相对应的传感器进行控制 (对应上述的控制传感器的工作状态） 和配置 （对应上述的调整成像参数）。 主控器 2可 经缓冲器 3为二个传感器提供输出图像数据的统一的像素参考时钟信号，传感器内部的锁 相环将由此系统时钟而产生自己的像素时钟信号。该控制器 2还为二个传感器提供统一的 启动控制信号。与右眼相对应的传感器输出的右眼图像数据 101和与左眼相对应的传感器 输出的左眼图像数据 102经如图 2所示的同步合成器形成左眼和右眼图像数据分别位于左 侧和右侧的并列式图像数据， 同步合成器将该并列式图像数据输入至主控器 2中，主控器 2将该并列式图像数据作为普通的二维图像进行压縮和编码，形成与并列式图像数据相对 应的 RGB图像数据。
主控器 2将 RGB图像数据输入至图 3所示的立体显示转换器 5中进行处理， 以形成 立体显示屏 12可识别的显示格式。
如图 3所示， 该立体显示转换器 5包括立体格式转换模块 501、 LCD接口驱动模块 502和输出方式选择模块 503， 该立体格式转换模块 501可将接收到的并列式的 RGB图 像数据转换为交叉格式， 如点对点显示格式（Dot by Dot)、 SUBPIXEL或棋盘式（checker board), 相应格式的转换模块是现有技术， 在此不再具体说明。 输入至立体显示转换器 5 的 RGB图像数据一路输入至该立体格式转换模块 501中进行格式转换， 另一路输入至该 输出方式选择模块 503的第一通道，该立体格式转换模块 501输出的交叉格式的图像数据 一路输入至 LCD接口驱动模块 502中， 另一路输入至该输出方式选择模块 503的第二通 道， 该 LCD接口驱动模块 502的输出输入至该输出方式选择模块 503的第三通道， 该输 出方式选择模块 503的三个通道可选择地与立体显示转换器 5的 LCD接口电连接。目前， 该 LCD接口驱动模块 502有三种， RGB、 CPU和串行 SPI。 立体显示屏 12通过 LCD接 口与该立体显示转换器 5通讯连接。
在此，主控器 2可向二个摄像头的微控制器发送片选信号， 以确定需要执行主控器 2 发出的指令的对象，设置片选信号有利于对成像系统进行调试，在二个片选信号均为选中 状态时， 即主控器 2向二个摄像头的微控制器群发指令。传感器的性能不尽相同， 某些参 数需要分别调整， 这个时候需要利用片选信号分别对左右传感器进行参数配置。
由于二个传感器采用统一的像素参考时钟， 因此， 在各传感器的已经配置好参数以 及启动一致的情况下， 二个传感器几乎可在同时向外输出原始的图像数据， 但是， 由于各 传感器是独立工作的， 因此， 无论控制的多么精确， 也很难保证各传感器输出图像数据的 同步性，通常会产生或多或少的延迟，而在该种条件下的延迟通常为相互间的最大延迟在 0.5行的范围内。 如图 2所示，该同步合成器包括与二个摄像头一一对应配置的左存储器 402和右存储 器 401， 与左和右存储器一一对应配置的左写控制模块 602和右写控制模块 601， 以及， 一个读控制模块 9和一个输出选择模块 7。左、右存储器均是读写操作可异步进行的异步 双端口，二个传感器输出左眼图像数据 102和右眼图像数据 101后，就被立即输入至同步 合成器的左写控制模块 602和右写控制模块 601中，并分别在左、右写控制模块的控制下 被写入与左存储器 402和右存储器 401中， 在此， 左、右写控制模块在控制写入时采用与 二个传感器相同的行场同步信号和像素时钟信号，写控制模块就相当于缓存器，根据与各 自相对应的存储器的容量将适当容量的图像数据逐步写入至存储器的指定地址中；而该输 出选择模块 7负责从左、右存储器中读出各图像数据， 并在读出的过程中完成合成， 形成 并列式图像数据，该读控制模块 9为输出选择模块 7提供控制读出的行场同步信号和像素 时钟信号，控制读出的行场同步信号与控制写入的行场同步信号同频率（即与各传感器的 行场同步信号同频率）， 控制读出的像素时钟信号使输出选择模块 7在控制读出的一个行 周期内将二个传感器的一行读出，并合并在新的一行内， 即在控制读出的一个行周期内包 含了二个传感器的一行数据，进而将左眼图像数据 102和右眼图像数据 101分别拼接在并 列式图像数据的左侧和右侧。合并时可以采用两种格式，如全分辨率并列式和半分辨率并 列式，其中，半分辨率并列式相当于对左眼图像数据 102和右眼图像数据 101均进行了横 向压縮。该控制读出的像素时钟信号与控制输出的行场同步信号的频率及每行的总像素有 关， 当采用全分辨率并列式合并格式时，控制读出的像素时钟信号的频率 =传感器的像素 时钟的频率的 2倍； 当采用半分辨率并列式合并格式时，控制读出的像素时钟信号的频率 =传感器的像素时钟的频率， 根据需要可以直接选择对应于左眼或者右眼的传感器发出的 像素时钟。
二个传感器的行场同步信号经过延时模块 11、像素时钟信号经过锁相环 8 (需要倍频 的时候， 即采用全分辨率并列式合并格式时） 输入至读控制模块 9中， 使读控制模块 7 根据上述要求产生控制读出的行场同步信号和像素时钟信号。
由上可知，二个存储器的容量要满足至少可以存储两行图像数据的要求，一行用来在 写控制模块的控制下进行写入，另一行用来在读控制模块的控制下进行读出。由于存储器 的缓冲作用，加上读出时采用单一的行场同步信号和像素时钟信号，这就实现了图像信号 的同步， 并且输出选择模块 7在读出时直接实现合成。
当然，该输出选择模块 7也可在读控制模块 9的控制下仅读取左眼图像数据或者右眼 图像数据， 以进行二维显示。 由于二个摄像头间会产生左右视差， 但是在不同的显示屏上显示的时候， 相同的视 差也会造成不同的感受。 另外， 不同的人对于视差的大小有不同的容忍度。 因此， 为了更 好的让使用者得到舒适的立体图像观感，则需要调节视差的大小。视差调节是通过输出选 择模块 7 在控制读出的一个行周期内针对二个存储器中存储的所要读出的行选择不同的 起始点和终止点， 即通过选择性读出的方式来实现的。 另外，二个摄像头在安装时要尽量使光轴位于同一水平平面上，使二个传感器输出的 图像数据尽量不存在上下视差， 但这就对安装精度提出了较高的要求。针对该问题， 除了 机械光学调整外，还需要通过电子调整的方法进行细调。上下视差的调整可通过去除开始 或者末尾的整行图像数据达到上下对齐的目的。在此，能够上下移动的最大范围由各存储 器的容量决定， 例如， 如果各存储器只能存储 10行图像数据， 则输出选择模块 7在读出 时也只能实现上下 10行， 相对 20行的移动， 消除上下视差后， 对于那些不齐部分的图像 一律去掉。 这样， 就会在图像的纵向视场上进行了部分压縮。 该成像系统还可以配置与主控器 2通讯连接的存储卡，另外该主控器 2还可与 SD卡 接口模块、 USB接口模块、 TV接口模块和 /或 HDMI接口模块通讯连接。
综上所述仅为本发明较佳的实施例， 并非用来限定本发明的实施范围。 即凡依本发 明申请专利范围的内容所作的等效变化及修饰， 皆应属于本发明的技术范畴。
